This is the actual fix. The compat mode changed (well, it didn't), but we were
not scheduling a style flush.
Then someone called getComputedStyle on an element in this document, and the
styles were thought clean, thus we didn't flush style, and we assert when style
resolution happened.

This patch basically does:
* remove StyleSetHandle and its corresponding files
* revisit #includes of related header files and change correspondingly
* change nsIPresShell::mStyleSet to be UniquePtr<ServoStyleSet>
* change the creating path of ServoStyleSet to pass UniquePtr
* change other mentions of StyleSetHandle to ServoStyleSet*
* remove AsServo() calls on ServoStyleSet
Some unfortunate bits:
* some methods of (Servo)StyleSet only accepts ServoStyleSheet while
many places call into the methods with StyleSheet, so there are many
->AsServo() added to sheets

The font face set is owned by the document now, and the shell knows about
refresh driver ticks. There's no reason for it to live in the pres context.

Unfortunately this means that we need to export a couple more headers, but that
should be ok.
In particular, we have to export some headers that are #included by
nsCSSFrameConstructor.h, because nsCSSFrameConstructor.h itself will now be
included in more places outside of layout/, by .cpp files that don't necessarily
have the ability to indirectly #include its other headers, unless we export
them.

Most of them just want GetRootFrame(), and there's no need to explicitly go
through the frame manager for that, we have a handy alias in the shell.

If a single element is inserted in the document, from the lazy frame
construction path we mark it as the restyle root.
It has no restyle data, and we weren't calling ClearServoData when its parent
was being removed from ClearServoDataFromSubtree, thus leaving the stale restyle
root.

In particular, even when there are no frames, we may have used the rule
cascades / stylist data (for different stuff, like font-feature-values, thus the
regressing bug).
Using the old rule cascades / stylist data without knowing it has changed is
wrong, thus the bug.
Now that media query change stuff is async and has a well-defined processing
point, we should be able to just call it without too much worry.
Also note that at the point the extra hints are passed, if there's no root frame
/ elements are not styled / etc, we'll optimize away the change hint.
The test-case intermittently fails without this patch, but I didn't manage to
make a better one, unfortunately :(

This fixes a bug where EnsureEventualDidPaintEvent needs to be called separately for each transaction id, but we skip it since mFireAfterPaintEvents is still true from the previous paint.
We now track the equivalent state by checking for the presence of mTransactions[aTransactionId], and correctly schedule an eventual didpaint for each id.

Much in the spirit of bug 1434474.
We right now call MediaFeatureChanges sync or async pretty randomly. This has
caused bugs in the past like bug 1413143.
Unify media feature changes, and only post them async, and flush them from
FlushPendingNotifications.
This also fixes a pre-existing problem where style wasn't flushed correctly from
getComputedStyle when there were pending media feature values.
